We didn’t suspend Alex Jones or Infowars yesterday. We know that’s hard for many but the reason is simple: he hasn’t violated our rules. We’ll enforce if he does. And we’ll continue to promote a healthy conversational environment by ensuring tweets aren’t artificially amplified.

"We didn't suspend Alex Jones or Infowars yesterday," said Jack Dorsey on Twitter. "We know that's hard for many but the reason is simple: he hasn't violated our rules. We'll enforce if he does. And we'll continue to promote a healthy conversational environment by ensuring tweets aren't artificially amplified."

He then went into more detail with subsequent tweets.

"Truth is we've been terrible at explaining our decisions in the past. We're fixing that. We're going to hold Jones to the same standard we hold to every account, not taking one-off actions to make us feel good in the short term, and adding fuel to new conspiracy theories.

"If we succumb and simply react to outside pressure, rather than straightforward principles we enforce (and evolve) impartially regardless of political viewpoints, we become a service that's constructed by our personal views that can swing in any direction. That's not us.

"Accounts like Jones' can often sensationalize issues and spread unsubstantiated rumors, so it's critical journalists document, validate, and refute such information directly so people can form their own opinions. This is what serves the public conversation best."

Criticisms have centred around Alex Jones' conspiracy theories. He has been called out for promoting untrue, virulent hypotheses about tragic events, like the Sandy Hook school shooting, which he claims is "completely fake".

In an earlier email to CNET, Twitter maintained Alex Jones and Infowars wasn't in violation of Twitter or Periscope's rules, but those rules are constantly under review. If content is posted that violates those rules, it is expected that Twitter will take action.
